Chronic Wasting Disease

It is impossible to discuss deer at all without talking about deer management, because there is there hardly a deer alive in America today that is not directly influenced by man. We control the water the deer drinks, the food that it eats, and the land that it lives on, and we regulate the manner, sex, and amount of deer harvested. The problem lies in the way we manage the deer herd. The time has come to practice Quality Deer Management.

The risk that deer present to motorist when driving and also the emergency personnel responding to emergency calls is unacceptable. Also the consideration of the potential health hazards, due to the parasites and diseases carried by deer, to our children as well as adults needs to be added to the call for a deer cull. The financial barriers to using and installing deer friendly preventative measures are impractical and with a cost effective way of managing urban deer population numbers, in the form of a cull, there are few other options which will be as effective and with minimal cost. With all of these considerations taken it is hard not to advocate and press for a deer management plan with the focus on reducing urban deer numbers by means of a

Bam!! All of a sudden you see a flash of brown cross in front of you, on your way home from seeing your parents, you try to stop to miss it but you end up hitting it and spinning out into the ditch causing you a lot of money in damage that has happened to your car. That happens to many people in a year According to State Farm, there were 1.23 million car accidents involving deer between July 1, 2011 and June 30, 2012. Many people think deer hunting should be illegal, but they don’t think about all the cat wrecks that happen due to them, how much crops they eat from farm land, also how much landscape they destroy from bucks making rubs and scrapes, they destroy a lot of fences, and how people use them often for food during the winter, all people

In the last 13 years, cases of Chronic Wasting Disease have increased to over 25% in bucks and over 10% in does (Marien). With CWD being such a deadly disease, the rising percentage of cases has led to decreasing deer populations. Because the spread of CWD has resulted in many deaths, fewer hunting tags are allowed in affected areas to help the deer herd get healthy again. It is possible, though, that as the populations grow back, CWD may also become more prevalent. Actually stopping this tragic disease is a challenge, but plans must be put in place to bring its spread to a halt. Therefore, it is important that hunters and the general public be informed of what CWD is, how it is spread, how it affects animals, and what can be done to

Chronic Wasting Disease (CWD) is a fatal neurodegenerative transmissible spongiform encephalopathy (TSE ) found in some white tailed deer. CWD is associated with diseases such as Mad-Cow disease, Scrapie, and Creutzfeldt–Jakob disease. With well supported evidence it is hypothesized that CWD originated from Scrapie. The causation of CWD is an abnormal form of PrPcwd prion. This prion is a naturally occurring protein found in mammals. Prions lack genome and are highly resistant to degradation. Chronic Wasting Disease can be transmitted by direct contact between the animals and/or on resources such as salt licks.

cows that were infected with BSE showed the symptoms early in the 1980's , they

"Mad Cow" disease or BSE has never been detected in the United States. No definitive links have been found between BSE and a human form of the illness.

Can you imagine the impact of a fatal disease on a population? Chronic Wasting Disease, or CWD for short, is a prime example in the whitetail deer herd. CWD is a fatal neurological disease, more specifically known as a type of transmissible spongiform encephalopathies (TSEs). In deer, this disease causes a characteristic spongy degeneration of the brains of infected animals, resulting in emaciation, excessive drinking and urination, abnormal behavior, loss of bodily functions, and death (Witkowski 3). With the discovery of Chronic Wasting Disease the question arises what exactly is this disease and how detrimental has and will CWD be on the population of whitetail deer?

Prions are linked to human health due to a person having abnormal proteins, which will give them a faulty gene and resulting in them inheriting

Bovine Spongiform Encephalopathy (BSE), also known as Mad Cow Disease has been found to have a causal association with variant Creutzfeldt-Jakob Disease (vCJD), which effects humans, and ultimately leads to death (CDC, 2015). This disease has been found in cattle in the UK, Canada and other countries. This disease has been controlled through several different means. In the UK, all animals over 30 months of age are removed from the food supply. In Canada and the United States, there is a ruminant feed ban which has prevented the continued spread of BSE. It's expected that “BSE should be eliminated from the Canadian cattle herd by about the year 2017” (CDC, 2015).

"Our findings open the possibility that some of the sporadic Alzheimer's cases may arise from an infectious process, which occurs with other neurological diseases such as mad cow and its human form, Creutzfeldt-Jakob disease," said Dr. Claudio Soto, professor of neurology at the University of Texas. Creutzfeldt-Jakob disease (CJD) is a so-called "prion" disease - meaning it is caused by misshapen protein molecules scientists call prions. Prions slowly destroy

Kuru was first seen in the mid-twentieth century and was at its peak in the late 1950s, due to the Fore tribe in Papua New Guinea having cannibalistic rituals for their dead. Every year 2% of their population would be killed off by the disease, which eventually led their tribe to the brink of extinction. It is thought that Kuru began when a Fore tribe member sporadically had developed Creutzfeldt-Jakob disease (CJD) and was later consumed after passing away. Creutzfeldt-Jakob disease (CJD) is a prion disease that spontaneously strikes about one person in a million each year (Deng, 2015). Prions are misfolded proteins that have the ability to make other proteins in the body misfolded, therefore being infected with one can start a surge of proteins being converted into more prion protiens (Minikel & Vallabh, 2013). Those who consumed

Has been found worldwide in all countries that raise sheep. In the US this disease is seen a lot in the western states.

Prion diseases are caused by proteinaceous infectious particles (more commonly referred to as prions). According to the CDC the term prion “refers to abnormal, pathogenic agents that are transmissible and are able to induce abnormal folding of specific normal cellular proteins.” Prions are always contracted one of three different ways. They can develop sporadically through a sudden genetic mutation. They can be inherited; prions are autosmol dominant, meaning that children of the infected have a fifty percent chance of inheriting the disease. Finally, prions can be ingested: either through consumption of infected meat or after exposure to poorly cleaned medical instruments.

Foot and Mouth (FMD) is recognized as a highly contagious viral disease which affects cloven-hooved animals, such as cattle (Bos Taurus) (Grubman and Baxt, 2004).
